Need help with ff4j framework

Currently we are using ff4j for feature toggling in our applications. We have created few features that are made on or off in an environment like UAT or DeV which means all the appliances in that environment will have the feature on or off. Now my requirement is to enable or disable the feature per application basis not environment based. Like f1is to be enabled for app 1 and disabled for app 2 in uat
